WILLIAM W. OOX,OF GREENE, ALABAMA.

QULTIVATOR,

SPECIFICATION forming part of Letters Patent No. 524,935, dated. August21,1894. I

Application filed March 1 2, 1 8 94;

of Alabama, have invented certain new and useful ImprovementsinCultivators; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it pertains to make and use it, referencebeing had to the accompanying draw- I ings, which form part of thisspecification My invention relates to an improvement in cultivator-s:and it consists in the novel features of construction hereinafter fullydescribed and especially referred to in the claims. 7

The object of my invention'is to provide improved lateral andinclination adjustment for the cultivator plows.

Referring to the accompanying drawings, Figure 1 is a perspective viewof the under side of the cultivator. Fig. 2 is a detached view of one ofthe plows. Fig. 3 is a similar view of the adjusting rack.

A is the central'beam of the cultivator and B the side beams connectedas shown at their forward ends to the said central beam so as to have anoutwardly swinging movement. Each side beam B is provided on its underside with a pivoted plate 0 having a stud D to which is pivotallysecured the plow stock E. Pivotally secured to this stock is the arm Fwhich leads upward and backward to the rear of stud D and secured to;its upper end is the plate'G provided with a series of adjusting holesG, whereby the same is clamped by bolt H to the slotted adjusting rack Iwhich extends inward toward the central beam. The slot in this rack issegmental so that the bolt H may be readily moved therein to acquire theproper lateral adjustment of the plow, while the openings G in plate Genable me to vary the inclination of the plows as will be readilyunderstood.

Serial No.503,325. (No model.)

A which serves to hold the side beam in proper adjustment. When the nutof the eye bolt is drawn up the arm is firmly clamped.

The plow of the central beam has no lateral adjustment, hence its stockis pivoted directly to the beam as shown at K, while its plate G is alsosecured thereto instead of to an adjusting rack as described of the sideplows. 7

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination of a cultivatorbeam, a plow stock adapted to swingbeneath the same, an arm extending from the stock, a plate pivoted tothe outer end of the arm and provided with a series of adjusting points,and a clamping bolt, substantially as shown and described. I

2. The combination of a cultivator beam, a plate pivoted to its underside, a plow stock pivotally connected to and adapted to swing beneaththe plate, a rack. over which the plate extends, arm F, plate G, andbolt H extending through plate G, the first named plate and the rack,substantially as shown and described.

3. A cultivator provided with a central beam, laterally movable sidebeams, racks on the inner sides of the side beams, adjustable plows onthe side beams which are held as desired by the racks, arms looselysecured to the said racks, and clamping eyes on the central beamthroughwhich the said arms extend,substantially as shown and described.In testimony whereof I affix my signature in presence of two witnesses.
